First, spasticity will be evaluated using the Modified Ashworth Scale (MAS). Based on this evaluation, the stimulation intensity for each muscle group will be determined and recorded in the system. Patients will wear the suit and receive stimulation while resting for 60 minutes. All MS patients will undergo treatment three days per week (with at least one day between sessions) for one hour per day over four weeks.

The Visual Analog Scale will be used to assess pain and fatigue. Patients will rate their pain and fatigue on a 10-cm line. "No pain-no fatigue" will be scored as 0 points, and "the worst pain imaginable-the worst fatigue" will be scored as 10 points.

The Fatigue Severity Scale (FSS) is a nine-item scale that measures the severity of fatigue and its impact on patients' activities and lifestyle. Each item is scored on a scale from 1 to 7. A score of 1 indicates strong disagreement with the statement, while a score of 7 indicates strong agreement. The lowest possible total score is 7, and the highest possible total score is 63. The higher the score, the greater the fatigue severity.

A nine-hole peg test will be used to evaluate hand function. The time it takes individuals to insert and remove the nine pegs from the holes will be recorded. Participants will perform the test with both their dominant and non-dominant hands.

Functional strength of the lower extremities will be assessed using the Five Times Sit-to-Stand Test. For this test, a standard-sized chair with a backrest (43-45 cm) is used. The patient sits on the chair with their back against the backrest. Each repetition of sitting down and standing up is counted. The time it takes to complete five repetitions is recorded using a stopwatch.

The TUG test measures functional mobility skills and risk of falling. For this test, participants stand up from a chair, walk three meters, turn around, walk back, and sit down again. The time it takes to complete this task is used to determine functional mobility. Completing the task in ≤10 seconds indicates normal functional mobility. Completing it in <20 seconds indicates good mobility, meaning the individual can walk without assistive devices and go out alone. Completing it in <30 seconds indicates a mobility issue, meaning the individual needs to use assistive devices and cannot go out alone.

A 10-meter walking test will be performed to evaluate patients' walking ability. Participants will walk 10 meters, and their time will be recorded with a stopwatch. The average time will be calculated based on three repetitions. Walking speed (m/s) will be calculated by dividing the walking distance (10 meters) by the average time obtained. Walking speeds are categorized as follows: <0.4 m/s indicates ambulation within the home, 0.4-0.8 m/s indicates limited ambulation outside the home, and >0.8 m/s indicates ambulation outside the home.

It assesses the patient's walking abilities over the past two weeks from their perspective. Each question is scored on a five-point scale. Patients are asked to rate themselves as follows: 1 = none; 2 = slight; 3 = moderate; 4 = severe; and 5 = very severe. A high score indicates difficulty walking.

Activities daily living will be assessed using the Functional Independence Measure (FIM). The FIM consists of 18 items that cover self-care, sphincter control, mobility, movement, communication, and social interaction. Scores range from 18 to 126.

It is a measure created by adding 18 multiple sclerosis (MS)-specific items to the Short Form 36 (SF-36), which contains 36 questions related to overall quality of life. Patients receive two separate scores, one for physical health and one for mental health. Higher scores indicate better outcomes. The scale's subparameters include physical health, physical role limitations, emotional role limitations, pain, energy levels, perceived health, social functions, cognitive functions, sexual functions, and overall quality of life. Total mental and physical scores are calculated based on the different coefficients of each sub-parameter.
